First time resurrected since graduation

I knew, theoretically, that this day might come.

You get a sewing maching - you start to use it - you start thinking, I could make that. You buy fabric.

And then you start drawing triangles and doing trigonometry before you cut.

Yes... I made Jonathan go find my scientific calculator so I could do square roots, and everything. a squared plus b squared equals c squared. And thus it goes. Using that equation was deep in my memory and so even though I kind of forgot, I really remembered. I know because when I checked my work, it came out true. That's good. My math teachers should be so proud!
